描述:

使用 callbacks.empty() 清空回调列表:

jQuery 代码:

// a sample logging function to be added to a callbacks list

var foo = function( value1, value2 ){

    console.log( 'foo:' + value1 + ',' + value2 );

}



// another function to also be added to the list

var bar = function( value1, value2 ){

    console.log( 'bar:' + value1 + ',' + value2 );

}



var callbacks = $.Callbacks();



// add the two functions

callbacks.add( foo );

callbacks.add( bar );



// empty the callbacks list

callbacks.empty();



// check to ensure all callbacks have been removed

console.log( callbacks.has( foo ) ); // false

console.log( callbacks.has( bar ) ); // false
